The Boreal Chickadee, Parus hudsonicus or Poecile hudsonica, is a small songbird in the tit family Paridae. Their breeding habitat is coniferous woods in Canada, Alaska and the northern edges of the United States. They are permanent residents, but sometimes move south in winter. They often forage with small flocks including other small birds in winter.
Adults have gray-brown upper parts with a brown cap and grayish wings and tail. Their face is mainly gray with white on the sides. Their underparts are white with brown on the flanks and a black throat. They have a short dark bill, short wings and a long notched tail.
They nest in a hole in a tree, using a natural cavity or sometimes an old woodpecker nest. The pair remains together year round and may mate for life. These birds forage on conifer branches or probe into the bark. They mainly eat insects and seeds. They will store food for later use.
The call is a husky grey-a-dee-dee, a variant on the call which gives chickadees their name.
